**Incorrect email setup in QuickBooks:** Wrong login credentials or outdated settings can prompt repeated password requests.

**Outdated QuickBooks Desktop or Outlook version:** Compatibility issues between QuickBooks and Microsoft Outlook can break the MAPI connection.

**Corrupted MAPI files:** Damaged MAPI subsystem files can prevent authentication.

Identifying the exact cause helps choose the most effective fix.
